In this case, spot color appears to make up for this deficiency. Spot color is directly printed according to the proportion of the chromatogram to allocate the required ink color. The color does not need to be controlled by point density, so the whole color is solid and looks more textured.

专色是金色和银色，但实际上潘通光谱中有成千上万种专色。如果所需要的颜色不在色谱上，也可以根据色彩大师的经验来调整所需要的颜色，来找到油墨的比例。济南台历挂历一般在高档书刊中起点缀作用，但多用于包装，使印刷色彩更有质感，视觉冲击力更强，如香烟包装等。

Spot colors are gold and silver, but there are actually thousands of spot colors in the Pantone spectrum. If the required color is not on the chromatogram, you can also adjust the required color according to the experience of color masters to find the proportion of ink. Jinan desk calendar is generally used in high-end books and periodicals, but it is mostly used for packaging, which makes the printing color more textural and has stronger visual impact, such as cigarette packaging.

台历打印设计要考虑到实际尺寸与日历宽度长度的比例;设应考虑实际尺寸的月历与长宽比:有的月历是方形的，有纵向长条的，也有横向长方形的，设应考虑实际尺寸与长宽比的关系，设计后尽量美观。

The design of desk calendar printing should consider the ratio between the actual size and the calendar width; the design should consider the actual size of the calendar and the length width ratio: some calendars are square, there are longitudinal strips, there are also horizontal rectangular, the design should consider the relationship between the actual size and the length width ratio, and try to be beautiful after design.

影响飞墨的要素

Factors affecting flying ink

(1)油墨黏渡过大，油墨在墨辊出口处被拉长，易产生飞墨，同时还会构成传墨不匀，使纸张拔毛脱粉，济南台历印刷纸张从橡皮布上剥离艰难，易花版、掉版等;黏渡过小，墨层团结不佳，易产生飞墨，同时易使油墨乳化，起浮脏、糊版、网点扩展，影响印刷产质量量。

(1) The ink is too sticky, and the ink is elongated at the outlet of the ink roller, which is easy to produce flying ink. At the same time, it also causes uneven ink transfer, which makes the paper hairy and powdery. It is difficult for Jinan calendar printing paper to peel off from the blanket, and it is easy to print and drop; It is easy to produce flying ink, emulsify the ink, float dirty, paste plate and dot expansion, which affect the printing yield and quality.

(2)墨辊上墨层愈厚，飞墨愈大。打样在铜版纸上，墨层厚度在1.2μm时，版上油墨只需抵达2.8g/m2就行;但用胶版纸印刷，版上油墨少要抵达4g/m2。遇到纸张性能对油墨黏附力不好的状况，易构成墨辊堆墨，从而产生飞墨。

(2) The thicker the ink layer on the roller, the larger the flying ink. For proofing on coated paper, when the ink layer thickness is 1.2 μ m, the ink on the plate only needs to reach 2.8g/m2, but for offset paper printing, less ink on the plate needs to reach 4G / m2. When the paper performance is not good for ink adhesion, it is easy to form ink roller pile, resulting in flying ink.

(3) 墨辊外表凹凸不平及外表干结龟裂时，局部油墨层加厚，墨雾量增大，易产生飞墨。

(3) When the roller surface is uneven and the surface is dry and cracked, the local ink layer thickens and the amount of ink mist increases, which is easy to produce flying ink.

(4) 印刷速度增加，飞墨增大。

(4) With the increase of printing speed, the flying ink increases.

(5) 空气相对湿度小，促进飞墨产生;湿度增大时，电荷减少，飞墨质变小。

(5) When the air relative humidity is low, it promotes the production of flying ink; when the air relative humidity increases, the charge decreases and the quality of flying ink decreases.
